Rearview mirror with buttons incorporating display
First Claim
1. A mirror for a vehicle comprisinga mirror housing;
- a reflector positioned in the mirror housing;
an electrical circuit including a switch coupled to the mirror housing for activating and de-activating the electrical circuit;
a sensor operably connected to the electrical circuit for sensing daylight and darkness;
a compact display on a front of the mirror housing including a button coupled to the switch to actuate the switch, the button including a face having a light-transmissive window, and further having marginal material around the window to define a border, and still further having outer material forming an outer region outside of the border, the window and the border both defining an identifying symbol for the button, and the marginal material having an appearance in daylight that contrasts visibly and noticeably with the outer material;
a light source positioned to direct light toward the window;
the electrical circuit being configured to automatically energize the light source to a first level to allow viewing and identification when in darkness and when the switch has de-activated the circuit, and further being configured to automatically energize the light source to a second level to allow viewing and identification when in darkness and when the switch has activated the circuit, and still further being configured to automatically energize the light source to a third level to allow viewing and identification when in daylight and when the switch has activated the circuit, and also the border being sharply visible due to contrast to the outer material when in the daylight to allow viewing and identification of the button when the switch has de-activated the circuit.

Abstract
An electrochromic mirror includes housing, a rearview mirror subassembly including a reflector in the housing, and an electrical circuit with switches adapted to interact with electrical systems in the vehicle. An elongated display area is formed in a face of the housing assembly, either under, aside or above the face. Switch buttons are positioned in the display area for operating switches in the electrical circuit. Where compact display is needed along with the button, the buttons each have a visible portion with a front symbol-forming window that is light-transmissive, and further with a perimeter made of a visible material that outlines and creates a border around the symbol-forming window, and still further with an opaque outer region that contrasts to the visible material. A light source is positioned to direct light toward each window. Each light source is operably connected to the electrical circuit and the electrical circuit is configured to variably energize and de-energize the associated light source when the one switch is activated and de-activated. By this arrangement, the perimeter is visible during daylight with the light source de-activated, and the perimeter and the symbol-forming window are visible during daylight with the light source activated. Also, the symbol-forming window is visible during night when the light source is activated to a low level of light to show the switch in de-activated and is visible during night when the light source is activated to a high level of light to show that the switch is activated.
